Answer:
(x, y) = (1, 1)
Step-by-step explanation:
Using the second equation to substitute for y in the first equation, we have ...
x = -2x +3
3x = 3 . . . . . . . add 2x
x = 1 . . . . . . . . .divide by 3
y = x = 1
The solution is (x, y) = (1, 1).
_____
If you have the graph, you can read the solution from it as the coordinates of the point where the lines cross.
Answer:
Yeah
Step-by-step explanation:
Step-by-step explanation:
y + 4 = -2x + 2
2x + y = -2
2x = -2 - y
x = -2 -y/2
Answer:
H(n) = -n^2+4+n
g(n) = n-1
Find g(h(n))
Step-by-step explanation:
hello :
g(h(n)) = g(-n²+4+n) =(-n²+4+n)-1
g(h(n)) =-n²+n+3
X=15. This is the Altitude theorem which is Altitude/Part = Altitude/Other part. In this question you would set up the proportion 9/X = X/25 and multiply cross products to get 225=X^2. Then you undo X^2 by doing the square route of 225 and then you get 15 as the final answer.
